Abstract
Numerical design optimization of the aerodynamic performance of
axial fans is carried out, maximizing the efficiency in a
designinterval of flow rates. Tip radius, number of blades, and
angular velocity of the rotor are fixed, whereas the hub radius
andspanwise distributions of chord length, stagger angle, and
camber angle are varied to find the optimum rotor
geometry.Constraints ensure a pressure rise above a specified
target and an angle of attack on the blades below stall. The
optimizationscheme is used to investigate the dependence of
maximum efficiency on the width of the design interval and on the
hub radius.
